Hello everyone!
I have a very disturbing problem (disturbing to me at least), the
exception mentioned in the title of this post occurs on the server
side but after the RPC executes.
I'll explain briefly, i have a DAO interface and a DAO implementation,
and besides, i have the two interfaces and class necessary to
implement a GWT RPC, i use the latter to define a way to call the
methods of the DAO from the client via a asynchronous call.
When i try to invoke the GWT RPC, the method in the DAO executes
without incident but before the result can be returned to the client
the exception takes place.
I am starting tomcat with the -Xms1024M flag in order to increase the
heap space but i guess there is some very unefficient memory handling
somewhere in there (in my app, not in tomcat nor in GWT) but i need to
know where before i can fix it... has this happened to anyone? my
guess is that the memmory suffices for handling the RPC but not for
serializing...
anyway, i decided to seek your advice... thanks in advance!
Rafael
Here is the root cause if i am not mistaken:
